How to order an alphanumeric column in MySQL?
To order an alphanumeric column with values like “100X, “2Z”, etc. use the ORDER BY. Let us first create a table −
mysql> create table DemoTable -> ( -> StudentId varchar(100) -> ); Query OK, 0 rows affected (0.52 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('2X');
Query OK, 1 row affected (0.21 sec)
mysql> insert into DemoTable values('100Y');
Query OK, 1 row affected (0.20 sec)
mysql> insert into DemoTable values('100X');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable values('2Z');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable values('2Y');
Query OK, 1 row affected (0.23 sec)
mysql> insert into DemoTable values('100Z');
Query OK, 1 row affected (0.17 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
Output
This will produce the following output −
+-----------+ | StudentId | +-----------+ | 2X | | 100Y | | 100X | | 2Z | | 2Y | | 100Z | +-----------+ 6 rows in set (0.00 sec)
Here is the query to order by an alphanumeric column in MySQL −
mysql>select *from DemoTable order by (StudentId+0), right(StudentId, 1);
Output
This will produce the following output −
+-----------+ | StudentId | +-----------+ | 2X | | 2Y | | 2Z | | 100X | | 100Y | | 100Z | +-----------+ 6 rows in set, 6 warnings (0.00 sec)
